The Boat/Rock Brainteaser ft Simone Giertz part 2/3

The video is a continuation of physics riddles with Simone. It begins with a recap of the first riddle about air resistance and terminal velocity, discussing how two spheres of the same size but different weights behave when dropped. The video then shifts to a light-hearted segment about encouragement and gold stars, followed by an explanation of what a transistor does. It concludes with a new riddle about water displacement, inviting viewers to return for the answer.

What determines the amount of air resistance experienced by objects of the same shape?

• Their weight

• Their surface area

• Their color

• Their temperature

Why do objects reach terminal velocity?

• Because air resistance equals gravitational force

• Because they stop moving

• Because they become weightless

• Because they change shape

Which ball experiences a higher gravitational force?

• The lighter ball

• The heavier ball

• Both experience the same

• Neither experiences gravitational force

What is the primary function of a transistor?

• To control high voltage with a low voltage

• To resist current

• To store electricity

• To transform voltage levels

What happens to the water level when a rock is thrown from a boat and sinks?

• It goes down

• It goes up

• It fluctuates

• It stays the same
